The command works in openvino 2018R5 and doesn't work in openvino 2019R1. I don't know why, could anyone help me?

In openvino 2019R1,I can successfully run "./classification_sample -d CPU -m *** -i ***", but errorly run “./classification_sample -d HETERO:FPGA,CPU”. And the error message is :

 

acl_hal_mmd.c:1393:assert failure: Failed to initialize kernel interface

classification_sample: acl_hal_mmd.c:1393: l_try_device: Assertion `0' failed.

 

For the environment of openvino 2019R1: 

system:centos 7.6.1810

kernel: 3.10.0-957.1.3.el7.x86_64

Acceleration Stack version:69528db6-eb31-577a-8c36-68f9faa081f6 (1.2 production)

The following is the detailed messages:

Dear lang:

This doesn't look like a DLA or OpenCL error message.  Seems like the board isn't being detected.  

Thanks for using OpenVino !

I am having the same issue in OpenVINO 2019R1. classification_sample -d CPU -m *** works but

classification_sample -d HETERO:FPGA,CPU does not.

(-d HETERO:FPGA,CPU worked fine in 2018R5). Also I am able to run all steps up to "Use the Intel® Distribution of OpenVINO™ toolkit" step 3

at the following tutorial link:

https://docs.openvinotoolkit.org/latest/_docs_install_guides_PAC_Configure_2019R1.html#hello_world_f...

The successful steps included "Program a Bitstream".

 

My environment is:

system:centos 7.6.1810

kernel: 3.10.0-693.el7.x86_64

Acceleration Stack version:69528db6-eb31-577a-8c36-68f9faa081f6 (1.2 production)

Can you provide any suggestions?

The issue was solved by setting the INTELFPGAOCLSDKROOT variable in init_openvino.sh to /opt/altera/aocl-pro-rte/aclrte-linux64 (the

folder for the 18.1.2 version of OpenCL RTE installed by OpenVINO 2019R1). Thanks to Jim Moawad from Intel Programmable Solutions Group.

Dear Arthur:

    Thanks for your solution!

     Another way is to modify the INTELFPGAOCLSDKROOT  in ***/intelrtestack/init_env.sh to /opt/altera/aocl-pro-rte/aclrte-linux64.

My init_openvino.sh is:    

source ***/intelrtestack/init_env.sh
export CL_CONTEXT_COMPILER_MODE_ALTERA=3
export CL_CONTEXT_COMPILER_MODE_INTELFPGA=3
export ALTERAOCLSDKROOT=$INTELFPGAOCLSDKROOT
source ***/openvino/bin/setupvars.sh

I am having the same issue with Lobo, Arthur.  But I don't have /opt/altera/aocl-pro-rte/aclrte-linux64. I install the dev version,not the rte version.

I am having the same issue with Lobo, Arthur

I install the dev(18.2GB) ,not the runtime(200MB) ,so I don't have /opt/altera/aocl-pro-rte/aclrte-linux64. 

and here is my init_openvino.sh

how can i do to solve this problem

source ***/tools/inteldevstack/init_env.sh
02
	export CL_CONTEXT_COMPILER_MODE_ALTERA=3
03
	export CL_CONTEXT_COMPILER_MODE_INTELFPGA=3
04
	export INTELFPGAOCLSDKROOT="***/tools/inteldevstack/intelFPGA_pro/hld"
05
	export ALTERAOCLSDKROOT="\$INTELFPGAOCLSDKROOT"
06
	export AOCL_BOARD_PACKAGE_ROOT="***/tools/inteldevstack/a10_gx_pac_ias_1_2_pv/opencl/opencl_bsp"
07
	***/tools/inteldevstack/a10_gx_pac_ias_1_2_pv/opencl/opencl_bsp/linux64/libexec/setup_permissions.sh
08
	source***/tools/inteldevstack/intelFPGA_pro/hld/init_opencl.sh
09
	export IE_INSTALL="/opt/intel/openvino/deployment_tools"
10
	source /opt/intel/openvino/bin/setupvars.sh
11
	export PATH=$PATH:***/inference_engine_samples_build/intel64/Release
12
	alias mo="python3.6 \$IE_INSTALL/model_optimizer/mo.py"
